Our Opinion

The OnePlus 6 (6GB RAM, 64GB) is a significantly better phone, but the Xiaomi Mi A2 (Android One) is significantly better value for money. Which phone should you buy? Depends on how much you want to spend!

The best looking OnePlus phone to date - has a polished refined design, with a glass rear panel, and three distinct (and beautiful) color options (plus the Marvel Avengers edition)

Excellent build quality

The phone is comfortable to hold, thanks to the curved glass rear

Face unlock works great in most conditions, and unlocks the phone in a fraction of a second (except in low light or under very bright sunlight)

There is also of course the fingerprint sensor at the back, if you wish to use that instead, and it works great too

OnePlus's excellent alert slider is there too (it has now moved to the right side of the phone) - and is now more simplified toggling between 3 simple states - ring, vibrate and silent, with a pop-up that tells you instantly which mode you are switching to every time

Excellent display - catches on to the modern 'notch' trend, with a tall screen ratio - the AMOLED screen is vivid, with punchy colours and great viewing angles - videos looks great, and you can also set your own custom colour temperature if you prefer

OxygenOS continues to be a huge differentiator for OnePlus - it strikes a great balance between keeping the base UI identical to stock Android but still adding a number of useful additions - like shortcuts, a dark theme, a scrolling screenshot capture tool, and controls for giving the on-screen buttons additional functions, night and reading modes, a choice of system fonts, and configurable colours for the notification LED - all in all, its a great software experience, that ticks the right boxes

Another interesting add-on is an optional gesture scheme that lets you get rid of the Android navigation buttons altogether, and gives you a full gesture based navigation scheme like the iPhone X - thus giving you even more screen space to play with - the gestures do take some time to get a hang of, but once you do, they will become second nature

There's also a Gaming Mode that not only suppresses non-essential notifications, but can also limit background apps' Internet usage, which can make a difference in online games - you can even route calls directly to the loudspeaker so you don't have to stop playing

Good set of dual rear cameras, significantly improved from the OnePlus 5T - especially in terms of portrait mode photos, low light performance, and video recording (including a new super-slow motion mode)

The rear cameras now also come with OIS

Decent (though not great) front camera, pretty similar to the OnePlus 5T - a software bokeh mode for the front camera is also there

Decent loudspeaker (pretty loud) - although it tends to get blocked when you hold the phone in landscape mode

Good (but not exceptional) battery life - will comfortably last the day with moderate to heavy use

Fast charging support, still one of the best in the business - the Dash Charger takes the phone up from zero to just over 50 percent in half an hour, and gives you a full charge in around an hour and a half

On the whole, the OnePlus 6 is good-looking, well crafted, extremely powerful - it is also a solid upgrade to the OnePlus 5T in almost all the departments such as display, performance, design and camera - and ultimately the OnePlus 6’s bang for buck is still about the best you can get in the smartphone world

Well built

The fingerprint reader on the back is in a natural position to comfortably unlock with either index finger

Contemporary, tall 18:9 display, brings the Mi Android One series up to modern standards

One of the best parts about the phone is of course the fact that it is part of the Android One series, which should mean guaranteed Android updates for at least 2 years + a stock, simple version of Android, with no unnecessary bloat

Butter smooth performance backed by a powerful Snapdragon 660 chipset, hardly seen at this low a price bracket

Stellar set of dual cameras on the rear - arguably the joint best at this price point, at par with the excellent Redmi Note 5 Pro - take nice photos in good and low light alike, and the bokeh shots too come out well

Very good selfie camera, with good bokeh shots - overall one of the best selfie cameras in this price bracket

Very loud loudspeaker, one of the best in this price bracket

Fast charging support

On the whole, the Mi A2 is a good, solid phone in this price bracket and you won't go wrong with it - it will compete strongly against the likes of Redmi Note 5 Pro (a bit cheaper, but doesn't have stock Android), and Honor Play (faster, better for gaming, but loses on the software)

2-minute Review [Negatives]

A little slippery because of the glass

Will also tend to pick up smudges very quickly

It's not the easiest to reach all corners of the newly enlarged screen - people who prefer more compact phones might have preferred a smaller-screen option for themselves

At 177g, the phone is a bit on the the heavier side too

While OnePlus does claim that the phone has water-resistance, it's not IP rating certified, which likely means that the protection is quite basic

The rear and front cameras are good, but not really up to the high benchmarks set by the likes of the iPhone X, the Galaxy S9, or the Pixel 2 - this continues to be the only one significant area, where you will be making a compromise over the best flagship smartphones, when you buy a OnePlus device (of course admittedly for a much lower price)

No 3.5mm jack, so if you want to use your existing standard-jack headphones, you will need to use an adapter (included in the box)

Brightness levels for the display could have been better - it's not the easiest phone to use under sunlight

The battery life could have been better - it will last you the day with moderate use, but it's not as good as the best of the competition
